GEOTHERMAL
Just saw a fascinating webinar and you should too if geothermal interests you.
It explains how techniques from fracking are creating a game-changer in the last few years that can reduce the cost of energy systems without fossil fuels.
🧵
The webinar by prof. Roland Horne from @Stanford is about Enhanced Geothermal Systems or EGS that he defines as using fracking to make the area between the infusion and extraction well permeable for water.
He focuses on @fervoenergy, a company founded by two @Stanford alumni (one from his program) that has for the first time in history used the horizontal boring technique from fracking in geothermal.
This eviscerates the last credibility of @Toyota regarding EVs.
They (esp. Gill Pratt) have been pushing the story we should buy their hybrids instead of full EVs because lithium batteries are and will stay the bottleneck
